I ironically got some of the best buds from a plant that was in a tent that got infected by spider mites last year. Maybe the stress? Lol
I inadvertently brought in and out a majestic palm from outside and somehow harbored spider mites in that plant. I only realized until there were full out webs on all my almost ready buds! The moment i saw the webs I was like, "No way! Not me!" They transferred over when i rubbed the majestic palm without realizing. I only thought to look at the palm after smoking some thought provoking bud. Sure enough there were thousands upon thousands on the palms. The palm got immediately destroyed.
The next few days were all vacuuming and carefully removing as much of those little things as possible, an uphill battle. A good technique is to wear gloves and plug the majority of the vacuum head allowing a pinhole air vacuum, increases the power and don't even need to get close to the buds this way. I didn't want to spray anything, hydrogen peroxide helped a little but there were too many.
I let them finish the last week or two and cut the entire plant as one (important), washed her immediately with baking soda/peroxide/water bath and hung to dry upside down. There will be spider mite crap and eggs left behind so do a thorough wash.
This is where you need to decide, if you kill them now, they will remain where you kill them. Otherwise, as the plant dries, the spider mites will travell along the tree to the base (which is now at the top), and bundle up in a big mass. You wipe them off with a tissue and be sure to catch the ones that try to climb further along the metal coat hanger. I have to use a wet tissue on the hanger hook to keep the mites from going anywhere from there. The plant stayed in the washroom the 2 weeks of drying. They were in the thousands and most likely the hidden eggs even hatched and walked out of the bud areas.
In the end, i managed to save the bomb buds, and only did all that to save the harvest at such a crucial time. Never bring in outdoor plants! And wash your hands when you go outside.
